With their programmable motion controller , tlc 63 drives are suitable for applications that in addition to motor control require simple sequential processing with fieldbus inputs and outputs 由于具有可编程运动控制器，除完成对电机的控制， tlc63驱动器还适用于需要对现场总线输入和输出进行简单顺序处理的应用场合。
Additionally , the query plans must require that these ranges be scanned in order either because there is an order by clause on t . a , or because an iterator within the plan requires that it consume the tuples in sorted order 此外，查询计划必须要求按顺序扫描这些范围，原因是对t . a应用了order by子句，或者计划中的迭代器要求它按排序顺序处理元组。
In the past , a developer either had to write the application so that message order didn t matter , or else temporarily cache message 3 until message 2 arrived so that the application could process the messages in the correct order 过去，开发人员或者必须编写应用程序，使消息顺序不出问题，或者在消息2到达之前暂时缓存消息3 ，以便应用程序可以以正确的顺序处理这些消息。
The parser that use the sax deal with the xml file in sequence , the data was not in the memory after operated and it ca n ' t modify the file , so it ca n ' t do random access to the file and is difficult to realize complex query . the scope of application of sax is small Sax接口的解析器只能对文档内容按顺序处理，处理完后并不将数据保存在内存中，也不能修改文档内容，故不能对xml文档做随机存取，难以实现复杂的查询，使用范围小。
